Infection Control
What are pathogens?
Disease-causing organisms or microorganisms capable of causing illness.
What is one primary goal of using proper body mechanics?
To prevent injury and complications during movement or activity.
Which healthcare professional is positioned at the top level of clinical operations and provides medical direction to nurses and medical assistants?
Physician.
A patient has a disease spread through respiratory droplets. Which precautions are indicated?
Droplet precautions.
What is one positive effect of consistent movement on the body?
Increased muscle strength, improved bone density, or better joint stability.
Which of these is a bloodborne pathogen: HIV, influenza spread by respiratory droplets, or malaria spread by mosquito bites?
HIV.
What is the center of gravity?
The center of a person's weight, which affects stability and balance.
What does a medical assistant's scope of practice define?
Tasks they may perform based on education, training, certification, and applicable rules or laws.
A person may have been exposed to an infectious disease but is not confirmed infected. What is this called?
Quarantine.
Which factor contributes most to stability: a wider base of support with a lower center of gravity, or a narrower base with a higher center of gravity?
A wider base of support and a lower center of gravity.
What is the difference between isolation and quarantine?
Isolation separates confirmed infected people; quarantine separates people who may have been exposed but are not confirmed infected.
When lifting a heavy object, what positioning principle helps prevent injury?
Use a widened base of support and lower the center of gravity.
What is the primary goal of team-based care?
Healthcare professionals collaborate to provide coordinated, high-quality patient care.
A disease remains infectious in the air over long distances. Which precautions are used?
Airborne precautions using respirators.
A patient needs long-term care and assistance with daily activities because they cannot safely live independently. Which facility is appropriate?
A nursing care facility or assisted living facility.
Which isolation precaution is used when a disease spreads through respiratory droplets?
Droplet precautions
What does tension refer to in body mechanics?
A stretching or pulling force along the length of a muscle or tendon.
What is the primary goal of an Accountable Care Organization (ACO)?
Create value through cost-effective, quality care with provider accountability.
According to the test, how long should hands be scrubbed with soap?
At least 20 seconds.
A patient has a minor injury and needs medical attention but does not need an emergency room. Which setting from the test is appropriate?
An acute care setting.
What is handwashing primarily effective at doing: sterilizing skin, mechanically carrying away microorganisms, or chemically killing all microbes?
Mechanically carrying away microorganisms using surfactants in soap.
What is torque?
A twisting or turning force on a joint or bone generated by muscle contraction.
Which facility is best for a patient recovering from a stroke who needs to regain strength, mobility, and independence?
A rehabilitation facility.
What does the chain of infection model show?
The process by which infection spreads, including interactions between agent, host, and environment.
Name two ways to reduce strain and improve stability when lifting or moving an object.
Any two: widen the base of support, lower the center of gravity, keep the object close to the body, maintain proper alignment.
